CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 732,516, dated June 30,1903. Application filed April 22, 1903. Serial No. 15 3,763,. (Nomodel.)

To all whom it may concern:

Be it known that I, ANTON CHRISTENSEN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Oar-Brakes; and Idohereby declare the following to be a full, clear, and exact descriptionof the inventiomsuchas will enable others skilled in the art to which itap-' pertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to that class of carbrakes in which the brakesare actuated by the momentum of the car and comprises particularly arail-brake operated by a clutch and drum onthe axle. v

The object of the invention is to form an improved apparatus of the kindstated, as will more fully appear in the followingdescription andclaims.

In the accompanying drawings, Figure 1 is a plan view of the apparatus,a portion only of the car-frame being shown. Fig. 2 is a side elevation,partly in section. Fig. 3 is a cross-section. Fig. at is a detail insection of the clutch and drum, and Fig. 5 is a perspective View of theadjustable sectional brakeshoe used in the apparatus.

Referring specifically to the drawings, (5 indicates portions of thecarframe; B, the wheels; A, the axle; E, a windingdrum joined to afrusto-conical head'O, which cooperates with a flange-collar C toproduce a The drum slidable on the axle, as will be understood.

D is a collar which fits loosely over the neck of the clutch-head and ispivotally joined to one arm of a bell-crank d, pivoted to vibratehorizontally on a bracket d attached to the car-frame. The other arm ofthe bell-crank is connected by link (1 to a vertically-acting bell-crankformed bya rock-shaft d supported in suitable brackets attached to thecar-frame and arms d and d thereon. The arm d is connected by rod 01 toan operating-lever 01 which extends through the floor of the car insuitable position to be operated by the driver.

The clutch may be operated from the other I end of the car by means of alever d similar to the lever d connected by a long rod (1 to the link dand the bell-crank.

It will be seen that appropriate movement of either lever will throw theclutch in engagement and rotate the drum to wind up the cable F attachedthere-to and operate the brake.

At each side of the car-frame, above the rails, is a guide-housing H, inwhich the brake-shoes H slide vertically to bear upon the rails: Thisaction is produced by a system of levers-connected to the cable F,comprising particularly a horizontal rock-shaft f, having an arm f, towhich the cable is attached, and arms 9 connected by links g, g, and gto levers G, which are fulcrumed to vibrate vertically in brackets 9supported on the housings H. These levers G are connected by linksh toshort levers h, which are fulcrumed at h on top of the housings andconnected by links h to lugs projecting from the top of the brake-shoes.The links 71. are so disposed that they may and will follow the shoe Hdown into the housing when the brakes are set.

Each of the brake-shoes, as shown in Fig. 5, consists of an upperportion-7 and a lower portion 8, connected by bolts 9, whereby they maybe spaced apart as desired to take up wear and adjust the shoes to thedistance of the car-body from the track. The parts of the shoe have ateach edge flanges a, which slide in appropriate guide grooves in thehousing. The brake-shoes are normally held up by springs G, connectedtothe'levers G and a fixture on the housing. The housings are spaced andsupported by braces I2 extending across between the same.

What I claim as new, and desire to secure by Letters Patent, is I 1. Thecombination with a car, of an axleclutch and winding-drum, hand-operated connections for throwing the clutch, vertically-slidable' railbrake-shoes, and connections between the drum and the shoes includingvertically-actinglevers over the shoes and connected thereto.

2. The combination with a car, a clutch slidable lengthwise on the axlethereof, a winding-drum operated by the clutch, rail- -IOO engagingbrake-shoes, and connections between the drum and the shoes, of anoperating-lever extending through the car-floor, and connections betweenthe lever and the clutch including connected horizontally and verticallyacting bell-cranks.

3. The combination with a car, rail-engaging brake-shoes thereon, aclutch member and drum slidable lengthwise on the car-axle, andconnections between the drum and the shoes, of a collar on the clutchmember, a bell-crank pivotally supported on the car and connected to thecollar to shift the clutch member, and means to operate the bell-crank.

4. The combination with a car, a housing thereon having vertical guides,of a braketween the rock-shaft and levers.

In testimony whereof I afiix my signature in presence of two witnesses.

ANTON CHRISTENSEN.
